November National Terrorism Advisory System Bulletin

“Since the last NTAS Bulletin issued in June 2016, our basic assessment of the global threat environment has not changed. We remain concerned about homegrown violent extremists who could strike the homeland with little or no notice. Events since the last NTAS Bulletin reinforce this. Accordingly, increased public vigilance and awareness continue to be of utmost importance. This was, for example, a crucial component of the swift response to the September terrorist acts in New York City and New Jersey.”
